how to get overall p value for categorical variable in GEE model?

[Janey Sewell]

Hi all,
Hoping someone can help me with the following:
I'm fitting a univariable model with GEE (xtgee chems i.a2_age_cat, family (poisson) corr(ar1) i(studyID) t( visit ) eform robust). My output shows me the p-value of each category but does anyone know how I can get the overall p-value (on its own, so not per category)? Thanks very much for any ideas, Janey
